Development of Highly Stereoselective 3+2 Cycloaddition usinga Chiral Iridium Borate Salt

摘要

Recently,radical reactions using photoredox catalysts have been garnering muchattention in the community of synthetic organic chemistry as a viable strategy for realizingmolecular transformations completely different from simple ionic reactions.However,owing to the lack of effective catalysts capable of selectively recognizing and controllingthe key intermediate,the radical ion species,catalytic stereocontrol of the radical reactionsunder photoredox conditions for synthesizing the structurally-defined molecules remainsunderdeveloped.
